Apple has created a loyal user base, but some Mac users still need to use Windows programs and the OS in general. Since Apple transitioned to the Intel processor for the brains of the Mac, the company provided an easy way to setup and install Windows in a dual boot configuration with OS X with its Boot Camp technology. In this article, we take a look at doing that.
Preparing your Mac to install Windows 10
Before you can install Windows on your Mac, there are some pre-requisites tasks you need to complete.
- A Windows license – Windows is not free for Mac, just like any PC, you need to purchase a license for it if you don’t own one. If you are a college student, you should be able to get a free license under your Microsoft Campus Volume License program such as Dreamspark (check your Library/Book Store or Faculty) or get a significant discount for students from the Education Store. Also under volume license programs where companies install Windows in bulk, OS X is considered as an appropriate base license. So check with your IT department for assistance with getting a copy. If you are interested in just trying Windows 10 on your Mac, you can download the Windows 10 Enterprise 90-day trial here. Otherwise, you can purchase a physical retail version, too. You can buy a Windows 10 flash drive from Amazon, or get it directly from the Microsoft Store. Please note that if you are performing a digital download, you can download an ISO file for Windows 10 directly in OS X using the Microsoft TechBench website.
- Have an empty thumb drive ready, 8 GBs or larger or a blank DVD or Blu-ray if you still use optical media.
- Determine which version and architecture of Windows that you Mac supports. By default, you need to choose a 64-bit version of Windows 10, since that is all that Apple supports on most models these days. Apple’s Boot Camp page provides a list of models along with versions and architectures of Windows that are supported. Also, make sure you select the appropriate edition, you can compare versions here.
- Make sure the latest version of OS X is installed. This will provide access to the latest Boot Camp drivers especially if you want to install the latest version of Windows on your Mac. Click the Apple menu then click App Store then install the latest updates for your Mac. Since versions of OS X are free, if your Mac is supported, then it is probably best you upgrade to the latest version which is OS X El Capitan – 10.11.2 (as of this writing).
- Download Boot Camp drivers in advance – Although the Boot Camp wizard takes care of this for you, it’s very unreliable based on my testing. Download it in advance from here.
Once these pre-requisites are out of the way, the next step is to set aside some space to install Windows 10. Open the Finder in the Dock then click Applications then scroll down then open Utilities. Double-click Utilities then open Boot Camp. Or press Command and space keys then type Boot Camp then press the Enter key.
The Boot Camp software is a simple wizard that guides you through the process of downloading drivers, partitioning your SSD/hard disk and starting the installation of Windows.
Check all of the following options then click Continue:
- Create a Windows 8 or later install disk
- Download the latest Windows support software from Apple
- Install Windows 8 or later version
Click Choose then browse then select the Windows ISO file downloaded from Microsoft TechBench.
If you have any relevant data on the thumb drive, it will be erased. Click Continue.
Wait while Boot Camp begins copying files to the thumb drive.
During the Boot Camp wizard, drivers for your Mac will be downloaded. This can take a very long time, so be patient.
If you get an error downloading drivers, see a troubleshooting section of this article for what you can do.
Determining Disk Space for Windows 10
After Boot Camp downloads your drivers, the next step is to identify the amount of space you will allocate to Windows 10 depending on individual factors. Future needs must be taken into account. Do you plan to always have Windows around? If so, consider giving Windows 10 a fair amount of space to operate. Consider the following:
- Updates for Windows that use disk space. Windows 10 is being delivered as a service, so apps built into the OS and updates will use up space over time. Windows 10 requires a minimum 16 GBs (32 bit) 20 GBs (64 bit) of space to facilitate the installation. Windows 10 uses about 9 GBs of space on disk.
- Apps – if you plan to download and install modern apps on Windows 10, you need to take this into consideration. Apps can use a significant amount of disk space, let’s not forget about traditional desktop apps that will require updates too.
- Data – personal files like documents, music, pictures, videos. If you plan to store any such content, you need to consider, is it worth keeping locally or maybe invest in an external hard disk or keep only the key files you need or work on regularly. This might be a perfect time to consider storing some files in the cloud if necessary. If you plan to use your Mac at work, your employer might configure your credentials to store files on their network instead of locally. For my purposes, I am using a Mac with 256 GBs of disk space, since Windows 10 will only be used for key apps and some files will be stored on an external drive, I will be allocating 56 GBs. You might be using a Mac with limited storage, consider carefully your needs now and in the future. If you don’t, you might have to back up and start over. If you work mostly with Office apps, then you can go with the bare minimum, if you are working with video and pictures, think big. The bare minimum I recommend these days is at least 50 GBs for Windows, and that’s cutting it short.
Once you have determined how much space you will allocate, use the mouse pointer to drag the knob to the left to assign the appropriate amount of space you will give to Windows.
Click Install, Boot Camp will prepare the partition then automatically restart your Mac.
This is an important part of the setup. Depending on the model Mac your using, you might have to hold down C or Option keys to present the boot options. In my case, I will hold down Option key that will present options for the volume I want to boot from. On screen, I am presented with two options, I will boot from the EFI Boot drive (yellow drive icon) where my Windows 10 installation files are stored. Use the left and right arrow keys to select it then press Enter.
It will take a short while then eventually boot into Windows setup. The setup wizard will look tiny on-screen, you will need to bare through this for the time being. I think with Microsoft’s new policy when it comes to revisions of Windows 10 regularly, it would be a good idea if they could work with Apple to at least include some basic class drivers into the latest builds of Windows. (I can keep dreaming).
